Chain oiler removal/install

[Eagle_Adam]

I'm putting an L20 back together, and just noticed this:

 

I'm curious how to replace it if I can and if I can't what's the best course of action?

[MicroMachinery]

Is this the engine that lost compression? Looks like the chain was rubbing on it.. ought not to be.

[darrel]

friction fit. I am sure they are available, just not sure where.

[Eagle_Adam]

No this is the new block micro....

 

So I can use vice grips to remove it? And hammer in a new one?

[datzenmike]

#13081-21000 L16s and L18s had them but not the L20Bs. Enough oil sprays out the chain tensioner and down from the cam to do the job so they were discontinued.

[darrel]

My l20b has it. '79 620 kc.

[datzenmike]

I can't find it listed on any L20B parts. Correction I gave up too soon. Can't find it listed on the 620 but

 

The '80 720 L20B and the later the Z22 and Z24 has a chain oiler.

 

So does the Z20E in the S110. The A10 and S10. So must admit it's likely to be on all L and Z series motors.

[Eagle_Adam]

All three of the L20b blocks I've torn down had em. :)

 

So, my question now is.... How do I go about removing the damaged one?

 

And if I can't would the best course of action be to cut off the existing one to prevent failure in the future?

Enough oil i think you must simply just famig out the sequence tensioner and down from the cam to do the job so that they might be easily revocated . . ..

Pull one from an old block.

 

I read somewhere that they can be removed and the hole plugged... I've looked but can't find it.

[EricJB]

It's probably in there pretty tight. If not it would get pushed out by the oil pressure. You may have to heat things up a bit.

Your pic is gone but if its what I am thinking, I was able to remove mine with just a pair of needle nose pliers.  Kinda twisted, up down motion, and it slid out.. Put it back in with light taps of a hammer

[Eagle_Adam]

i took a vice grip to it, no luck........

 

 

am i gunna hurt anything leaving it the way it is? 

[datzenmike]

The oil spray is directed to the side? on this? If it breaks off later won't it just spray out forward onto the timing cover? Easy out?

[Stoffregen Motorsports]

If you've damaged it further by trying to remove it then I would definitely take it out. If you really can't get it out then cut it off and EZ out it or drill it out a little at a time and then use the EZ out. Or you could smack it side to side (gently) and then try.

 

A new one wil hammer in, but if it goes in too easily, peen around it with a center punch.

 

Make sure the new one is clocked properly.

[Z-train]

My l20b has it. '79 620 kc.

None of mine do.

[datzenmike]

Bill, do you mean the 6 cylinders??? I remember reading something about missing oiler pegs. Maybe on the later L28s???

[Eagle_Adam]

long story short i left it, the only other option was to cut it off and take an easy out to it........ just plain not happening 

[darrel]

I don't recall having that in any of the z car engine blocks. 

 

You just need patience to get the oiler out.
